"Intelligent Dance Music", an often debated term for a style of electronic music (as "intelligent" sounds pretentious and it's not really "dance music") that encompasses a confusingly wide area of music. Mostly enjoyed by computer nerds and LSD-heads, mostly a combination of both. Known for being more cerebral than many forms of music, thus "intelligent". Listeners of this form of music are generally stereotyped as pretentious musical afficionado pricks.
